Commutator technique for the heat kernel of minimal higher derivative operators
Andrei O. Barvinsky, Alexander V. Kurov, Władysław Wachowski
We suggest a new technique of the asymptotic heat kernel expansion for minimal higher derivative operators of a generic -th order, , in the backgrou…
On the origin of almost-Gaussian scaling in asymptotically safe quantum gravity
Maximilian Becker, Alexander Kurov, Frank Saueressig
The gravitational asymptotic safety program envisions the high-energy completion of gravity through an interacting renormalization group fixed point, the Reuter fixed point. The pr…
Asymptotic freedom in (3+1)-dimensional projectable Horava gravity: connecting ultraviolet to infrared
Andrei O. Barvinsky, Alexander V. Kurov, Sergey M. Sibiryakov
We investigate the renormalization group flow of projectable Horava gravity in dimensions generated by marginal operators with respect to the Lifshitz scaling. The flow pos…
